Dilution
Dilution is when more solvent is added to the solution that makes the concentration lower. The equation for dilution is:
M1V1 = M2V2
M1 = concentration of the first solution
V1 = volume of the first solution
M2 = concentration of the second solution
V2 = volume of the second solution
Volume can be any unit as long as they match each other.
Example: You have 1 L of a 0.125 M aqueous solution of table sugar. You want to dilute the solution to 0.05 M. What do you do?
To solve the problem, you simply plug in the numbers you know:
(0.125 M) (1 L) = (0.05 M) V2
2.5 L = V2
Using the equation, you determine that the volume of the diluted solution should be 2.5 L. So you add enough water to the first solution so that the solution's volume becomes 2.5 L.
